Intro to Computer Science Module 05 - Repetition (For and While Loops)

In this module we are looking at how we can repeat sections of code as needed. For this, we commonly use a loop. Loops can be broken down into two main types, conditional loops (the while loop) and counting loops (the for loop). We'll look at these in Python breaking down how to move through lists of data.
We'll also look at data validation using a loop, and the creation of sentinel loops to allow a user to run a file for a long as they need.
